"The New Walk Game" - New Walk is about a mile long pedestrian lane in Leicester.
In turns you'd be allocated each woman that walk past in the opposite direction. If she turned off the lane before actually walking past you that didn't count. You were allowed 2 passes each for truly horrific looking women, but you had to use these wisely.
Much un PC hilarity was had when a mate, having used all his passes, was next for the really fat, really ugly woman in a wheelchair.
There were many attemptys to cheat the game, including a prolonged spell by one mate chatting to a tramp (you had to actually be walking up New Walk for it to count.
I invented the game "Dog".
Basically, you see a dog, point at the dog and say "Dog".
If you see a dog in a bag or on a bike, that's 2 points.
You can't claim a point for seeing the same dog twice.
Basically, you play for life.
I invented a similar game called "Wheelchair-bound", but it was fraught with devilish difficulty.
